Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water gate control in water conservancy projects, in particular to a mechanical device for displaying the opening of a gate. Background Art
[0002] In water conservancy projects, gate hoists lift and lower gates, requiring precise gate height measurement to indicate gate position and control flow. Currently, a common measurement method involves installing a height indicator on the gate hoist. An encoder records the number of wire rope drum rotations, allowing the length of the wire rope and lift height to be calculated.
[0003] Traditional gate opening display devices mostly rely on electronic sensors or complex mechanical transmission structures. When the number of wire rope winding layers on the drum on the gate hoist is multiple, the winding diameter of each layer is different, resulting in a certain error in the take-off and landing height calculated by the number of drum rotations. When the gate needs to be taken off and landed urgently in the event of a power outage, or when the gate opening needs to be known in the event of a power outage, the height indicator may not work properly. The height indicator is connected to the drum shaft through a coupling. When the coupling is damaged or loose, the indication will also produce errors or even no indication, and maintenance is also more troublesome. Utility Model Content
[0004] The purpose of the present invention is to provide a mechanical device for displaying the gate opening, so as to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a mechanical device for displaying the gate opening, comprising a fixed base, a thin steel wire rope, a thin reel, a counterweight, a steel wire rope, and a double reel. The fixed base is installed on the top platform, one end of the thin steel wire rope is connected to the gate, and the other end of the thin steel wire rope is wound in the thin reel, and the thin reel is rigidly connected to the double reel. The double reel is connected to the counterweight through a thin steel wire rope.
[0006] Preferably, both ends of the thin reel are annular rope grooves and the middle of the thin reel is a spiral rope groove, and when winding the thin steel wire rope, the annular groove transitions to the spiral groove.
[0007] Furthermore, the two ends of the thin reel are designed as annular rope grooves, while the middle part is a spiral rope groove. When the thin steel wire rope is wound on the thin reel, it will first start from the annular groove and then transition to the spiral groove, which helps to ensure that the thin steel wire rope can transition smoothly during the winding process, reduce friction and wear, and at the same time improve the operating efficiency and reliability of the entire mechanical device.
[0008] Preferably, the rope groove depth of the thin reel is much greater than the diameter of the thin steel wire rope.
[0009] Furthermore, the depth of the rope groove is much greater than the diameter of the thin steel wire rope, so that the thin steel wire rope has enough space in the rope groove for winding and unwinding, reducing friction with the edge of the rope groove, extending the service life of the thin steel wire rope, and also improving the stability and accuracy of the mechanical device.
[0010] Preferably, the thin steel wire rope pressure plate on the thin reel is installed on the end face of the thin reel, and is grooved on the end face and connected to the annular groove.
[0011] Furthermore, a pressure plate is installed on the end face of the thin reel, and a groove is cut on the end face to connect to the annular groove. This installation method helps to ensure that the thin steel wire rope can be firmly fixed on the thin reel during the winding process to prevent it from slipping or loosening. At the same time, the slotted design allows the thin steel wire rope to smoothly transition from the annular groove to the space under the pressure plate, further improving the operating efficiency of the mechanical device.
[0012] Preferably, the thin reel is fixed to the double reel shaft by means of set screws.
[0013] Furthermore, the thin reel and the double reel shaft are fixed with set screws. This fixing method has the advantages of simple structure, easy installation, and reliable connection. It can effectively ensure the rigid connection between the thin reel and the double reel, and improve the stability and durability of the entire mechanical device.
[0014] Preferably, a pointer is connected to the counterweight, and a scale is provided inside the pointer.
[0015] Furthermore, a pointer is connected to the counterweight, and a scale is provided inside the pointer, so that when the gate opening changes, the position of the counterweight will also change accordingly, thereby driving the pointer to move on the scale. By observing the position of the pointer on the scale, the gate opening can be intuitively understood, thereby improving the readability and ease of use of the mechanical device.
[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:
[0017] When the gate is lifted, due to the presence of the counterweight, the double drum drives the thin reel to rotate, and the excess wire rope will be wound into the thin reel, and the thin wire rope will remain straight. When the gate is lowered, the gate will pull the thin wire rope, and the thin wire rope will be pulled out of the thin reel. The thin reel will drive the double drum to rotate and pull up the counterweight. When the gate is lifted or lowered, the counterweight will drop or rise accordingly. By observing the relative position of the pointer and the scale on the counterweight, the current opening of the gate can be accurately read, which is not limited to the form of a hoist, is directly connected to the gate, and can more intuitively and accurately display the gate opening. It adopts a purely mechanical structure, has strong environmental applicability, and is simple to maintain. BRIEF DESCRIPTION OF THE DRAWINGS
